When the n8n mongodb node runs, it creates a lot of connections to the DB, and seems like it’s not closing the connections after it’s done with the task.
My n8n setup runs every 5 minutes and queries from the mongodb node.
The version is 1.8.2

Hey @reev_ranj,
Not yet, The weekend got in the way and a couple of other issue I had to get to. I don’t think we have changed anything in the node recently though so this will likely still be an issue that we need to resolve.
ok Sure, @Jon .
Thanks for the update.
Please update here when this issue has been examined.
Temporarily we have increased the connection capacity of our MongoDB cluster as a workaround.

Hi there, any updates on this issue? Just noticed my workflow fails because the MongoDB connection limit is exceeded, as the connections don’t close…
Hey @tom.jdg,
Not yet, I have added it my todo list but I have some other issues to look into first.
Alright! Glad to hear the issue is on your to do list. Thanks for the quick response 
I might’ve found a fix for anyone having the same issue: I added the maxIdleTimeMS option to my connection string in n8n. So far it seems to work and connections close themselves automatically after the specified time.

That looks like a good solution for now, Looking at the node we are calling the close so it should be working 
Will continue looking around.
